DESCRIPTION
●The LT ®1506 is a 500kHz monolithic buck mode switching regulator functionally identical to the LT1374 but optimized for lower input voltage applications. It will operate over a 4V to 15V input range compared with 5.5V to 25V for the LT1374. A 4.5A switch is included on the die along with all the necessary oscillator, control and logic circuitry. High switching frequency allows a considerable reduction in the size of external components. The topology is current mode for fast transient response and good loop stability. Both fixed output voltage and adjustable parts are available.
●FEATURES
●■ Constant 500kHz Switching Frequency
●■ Easily Synchronizable
●■ Operates with Input as Low as 4V
●■ Uses All Surface Mount Components
●■ Inductor Size Reduced to 1.8µH
●■ Saturating Switch Design: 0.07Ω
●■ Shutdown Current: 20µA
●■ Cycle-by-Cycle Current Limiting
●APPLICATIONS
●■ Portable Computers
●■ Battery-Powered Systems
●■ Battery Charger
●■ Distributed Power
